detailed description

Specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It is understood that the drawings are for the purpose of illustration

1 is a perspective schematic view of an energy filling port assembly in accordance with an embodiment of the present invention. As can be seen from the figure, the energy filling port assembly includes an energy filling port 1 and a cover body 2 suitable for shielding it to avoid intrusion of rain, dust, etc., and to ensure the appearance of the body. According to the illustration, the cover 2 has an outer shape adapted to match the energy filling opening 1.

A mandrel 21 is fixed to the lid body 2, and a chute 22 is formed on the outer peripheral surface of the mandrel. The energy filling port is mounted to the vehicle body through an attachment such as a fender, in which a sleeve 11 is fixed, a slider is formed on the inner wall of the sleeve (see Fig. 2), and a spring 12 for pushing the cover outward. In the configured energy fill port assembly, the mandrel on the cover is inserted into the sleeve and the slider is placed within the chute 22 to slide relative thereto.

When the cover 2 is opened, the spring pushes the cover outward. Since the slider is always placed in the sliding slot, the guiding of the sliding slot defines the movement track of the cover, which can be realized when the spiral portion of the sliding groove engages the slider. The output of the moment is such that in the illustrated example the cover is rotated laterally relative to the energy fill port. It will be appreciated that the lateral rotation herein includes a rotation of the vehicle body that is substantially parallel to the energy fill port or substantially parallel to the energy fill port to the energy fill port.

It will be understood by those skilled in the art that in another alternative embodiment, the mandrel can also be fixed to the energy filling port to fix the sleeve to the cover. Alternatively, in still another alternative embodiment, the chute may be formed on the inner circumferential surface of the sleeve to form a slider on the surface of the mandrel. It is conceivable that in these various embodiments, in the energy filling port assembly, the mandrel or sleeve provided with the chute will pass The above-mentioned chute is used to guide the movement track of the cover body as a guide member in the energy filling port assembly.

In the present application, a mandrel is taken as an example of a guide. In accordance with the teachings of the present specification, those skilled in the art can correspondingly utilize the invention in the example of a sleeve as a guide. It will be appreciated that the present invention is applicable to other forms of guides having chutes, and is not exhaustive herein, but it will also fall within the scope of this application.

2 is a schematic view of the mandrel in the energy filling port assembly of FIG. 1 mated with the sleeve. As can be seen from the illustration, when the spring 12 pushes the cover to the left in the drawing, the mandrel 21 will slide to the left relative to the sleeve 11. Since the position of the slider 13 in the sleeve is fixed, when the spiral portion of the chute on the mandrel engages the slider, the mandrel will rotate circumferentially while generating a circumferential rotation, which causes the mandrel to rotate with the mandrel. The lateral rotation of the fixed cover bodies opens an energy filling port such as a fuel filler port or a charging port of the vehicle.

3 through 7 are detailed schematic views of a mandrel for an energy filling port assembly in accordance with various embodiments of the present invention. It can be appreciated that in these specific examples, the chute 22 has a helical portion. One of ordinary skill in the art can select the specific shape details (e.g., angles, etc.) of these helical portions, as well as the number of chutes, as desired. It is conceivable that appropriately increasing the number of chutes will facilitate the stability and reliability of the combination of the chute and the slider, so that the opening and closing of the cover are smoother, more stable and more reliable.

It can be understood that the energy filling port assembly is driven by the thrust of the spring, and the output of the torque is realized by the cooperation of the slider on the sleeve and the chute on the mandrel and defines the movement trajectory of the mandrel and thus the cover. Based on this, the present invention controls the speed or direction of the relative movement of the cover of the energy filling port assembly by special design such as increasing damping of the chute, and can avoid the energy filling port caused by the slider striking the end of the chute. The rebound and jitter of the cover.

For example, damping elements can be provided in the chute, for example on the appropriate section of the chute, for limiting the movement of the slides, which can be distributed continuously or intermittently in the chute, reducing the mandrel relative to the sleeve The speed of movement of the cylinder, thereby reducing the speed of movement of the cover of the energy filling opening, ultimately reducing the impact of the cover at the end of the moving stroke, improving or avoiding the rebound and shaking of the cover. Specific implementations of these dampers may be features disposed on the sidewall or bottom of the chute, such as, but not limited to, protrusions, cushions, or increased helix angles of the chutes, and the like. It will be appreciated that the provision of these dampers at the ends of the chute will more effectively affect the motion characteristics of the cover at the end of the opening action.

In connection with the embodiments of Figures 3 through 7, some exemplary arrangements for preventing springback and jitter on the mandrel are described below.

First embodiment

In this embodiment, a damping portion for restricting the movement of the slider is provided in at least one of the chutes 22. Specifically, it can be seen that the damper portion is located at the end of the chute, which is a section of the opposite side wall 22a at the end of the at least one chute, and the spacing of the section opposite the side wall 22a gradually contracts toward the end of the chute, so that The chute tapers at the end. The gradual contraction of the spacing of the pair of side walls may be formed by gradually raising one of the side walls of the chute or gradually increasing both side walls.

It will be appreciated by those skilled in the art that, according to various embodiments, such side wall sections that are gradually contracted at the end pitch may also be provided in a plurality of chutes or all chutes, and provided in each chute. This setting can be either the same or the same.

With this arrangement, it can be understood in conjunction with FIGS. 2 and 3 that when the end of the chute 22 reaches the slider 13, the spacing of the section of the side wall 22a at the end of the (at least one) chute faces the chute. The end gradually contracts, so that the chute is narrowed at the end, so the friction between the side wall of the chute and the slider is gradually increased, so that the moving speed of the mandrel 21 is gradually slowed down. It can be understood that this makes the cover of the energy filling port assembly gradually slow down and stably reach the stationary state when rotating to the end of the stroke, avoiding the generation of intense inertial energy, thereby effectively preventing the rebound and shaking of the cover body.

Second embodiment

In this embodiment, a damping portion for restricting the movement of the slider is provided in at least one of the chutes 22. Specifically, it can be seen that the damper portion is located at the end of the chute, and is a section of the bottom portion 22b at the end of the at least one chute, and the bottom portion 22b of the section is gradually raised toward the end of the chute.

It will be appreciated by those skilled in the art that, depending on the embodiment, such a bottom section that is gradually raised at the end may be provided in a plurality of chutes or all chutes, and this is provided in each chute The settings can be corresponding or identical.

With this arrangement, it can be understood by referring to Figs. 2 and 4 that when the end of the chute 22 reaches the slider 13, a section of the bottom portion 22b at the end of the (at least one) chute is gradually raised toward the end of the chute. Therefore, the radius of the mandrel of the corresponding portion is gradually increased, so the frictional force between the slider and the slider is gradually increased, so that the moving speed of the mandrel 21 is gradually slowed down. It can be understood that this makes the cover of the energy filling port assembly gradually slow down and stably reach the stationary state when rotating to the end of the stroke, avoiding the generation of intense inertial energy, thereby effectively preventing the rebound and shaking of the cover body.

Third embodiment

In this embodiment, a damping portion for restricting the movement of the slider is provided in at least one of the chutes 22. Specifically, it can be seen that the damper portion is located at the end of the chute, and is a soft cushion 22c disposed on the bottom of the chute at the end of the at least one chute. It will be appreciated that the flexible cushion 22c can be formed from a soft pad such as, but not limited to, a soft rubber, and secured in place by, for example, but not limited to, bonding, stapling, and the like. In an alternative embodiment, the soft cushion is disposed at the end of the chute, and when the slider reaches the soft cushion, it can hit the end surface of the soft cushion, and the reaction is delayed due to the absorption of the soft cushion. The force is relatively gentle, so it can alleviate the impact of the slider and the end of the chute, avoiding the generation of intense inertial energy. In another optional embodiment, the soft cushion may be arranged to gradually become thicker toward the end of the chute, and may be frictionally moved from the soft cushion when the slider reaches the soft cushion, thereby Play a buffering role.

It will be appreciated by those skilled in the art that such soft cushions may also be provided in a plurality of chutes or all chutes according to different embodiments, and such an arrangement provided in each chute may be Corresponding or identical.

With this arrangement, it can be understood in conjunction with FIGS. 2 and 5 that, when the slider 13 reaches the end of the chute 22, due to the presence of the soft cushion 22c on the bottom at the end of the (at least one) chute, Therefore, the sliding groove of the mandrel gradually slows the movement of the mandrel by the impact force or friction between the soft cushion and the slider. It can be understood that this makes the cover of the energy filling port assembly gradually slow down and stably reach the stationary state when rotating to the end of the stroke, avoiding the generation of intense inertial energy, thereby effectively preventing the rebound and shaking of the cover body.

Fourth embodiment

In this embodiment, a damper portion for restricting the movement of the slider is provided in the chute 22. Specifically, it can be seen that the damper portion is located at the end of the chute and is a substantially axial extension 22d formed at the end of the chute. The extended section 22d and the end of the chute may have a smooth transition, and the adjusted end is substantially parallel to the axial direction of the mandrel. It will be appreciated by those skilled in the art that in this embodiment it is desirable to have such an expansion section formed at the end of each chute, and such an arrangement provided in each chute may be corresponding or identical. .

With this arrangement, it can be understood in conjunction with FIGS. 2 and 6 that after the mandrel 21 is moved to the substantially axial extension 22d of the slider 13 into the end, the mandrel is substantially restricted from its circumferential movement, thereby Moving in the axial direction, the cover 2 cannot continue to rotate laterally. It can be understood that the expansion section 22d causes the cover of the energy filling port assembly to be gradually rotated and rebounded at the end of the rotation to the end of the stroke, and finally only basically It moves in the axial direction without rotating, thereby avoiding the generation of intense inertial energy in the circumferential direction, thereby effectively preventing the problem of rebound and shake of the cover.

Referring to FIG. 6 , it can be understood that, for the energy filling port assembly of the mandrel adopting the embodiment, when the cover body is closed, the cover body needs to be pressed axially for a short period (the slider is withdrawn from the axial extension section). After that, the cover can be rotated and closed. An improvement to this situation is that the natural state position of the spring 12 can be adjusted such that the slider just reaches the starting position of the extended section when the spring reaches the natural state position. It is conceivable that when the spring reaches this position, the spring force will become a pulling force, and due to gravity and inertia, the slider can finally stop at a position slightly to the right of the starting position, that is, just entering the extended section. This will continue to maintain the original open and close mode, while reducing rebound and jitter. In an alternative embodiment, depending on the specific needs, it may also be arranged that the slider substantially reaches the starting position of the extended section when the spring reaches the natural state position, or reaches the vicinity of the starting position of the extended section.

This arrangement for the spring can also be extended to other embodiments. Thus, when the cover is opened such that its movement trajectory reaches a starting position corresponding to the damper portion, the spring reaches a natural extension state. In combination with the specific situation, according to the actual effect that needs to be achieved, the spring can be naturally extended when the cover body reaches such that its movement trajectory substantially reaches the start position corresponding to the damper portion or near the start position of the damper portion. status. It will be appreciated that this will more advantageously limit the rebound and jitter of the cover at the end of the opening stroke.

Fifth embodiment

In this embodiment, a damping portion for restricting the movement of the slider is provided in at least one of the chutes 22. Specifically, it can be seen that the damper portion is located at the end of the chute, and is a protrusion 22e disposed on the sidewall of the chute near the end of the at least one chute, which is adapted to enter the end of the chute at the slider. At the moment, it is scraped and squeezed by contact with the slider, and then the slider is restrained at the end of the chute after the slider reaches the end.

It will be appreciated by those skilled in the art that, depending on the embodiment, such projections may also be provided in a plurality of chutes or all chutes, and such an arrangement provided in each chute may be corresponding Or the same. In an alternative embodiment, the protrusions in the different chutes may be arranged to be staggered back and forth along the movement track provided by the chute, so that the respective sliders in the different chutes are successively scraped and squeezed. Instead of simultaneously scraping and squeezing to the corresponding protrusions, the movement of the slider is gradually and sequentially restricted to achieve a better damping effect.

In addition to the illustrated example, in an alternative embodiment, it may also be provided on one side wall of the chute. More than one protrusion is placed, or one or more protrusions are respectively disposed on the two opposite side walls.

With this arrangement, it can be understood with reference to Figs. 2 and 7 that the projection 22e at the end of the (at least one) chute causes the relative slip of the slider to slow down when the slider 13 reaches the end of the chute 22. And the slider can be stuck at the end of the chute. This enables the cover of the energy filling port assembly to be stably held in position when rotated to the end of the stroke, thereby avoiding the generation of severe inertial energy, thereby effectively preventing the rebound and jitter of the cover.

Based on the above description, those skilled in the art will readily expand the mandrel of the foregoing embodiments into other forms of guides suitable for use in energy fill port assemblies. Likewise, those skilled in the art will be able to incorporate these guides into a conventional energy fill port assembly to provide an energy fill port assembly in accordance with the present invention. Due to the presence of the damper on these guides, the resulting energy fill port assembly will steadily slow down at the end of the opening stroke without the problems of springback and jitter that occur when the cover is opened.

Figure 8 is a schematic illustration of an energy fill port assembly having magnet components. Two magnet members 14 are provided at the energy filling port 1 as shown in the drawing, and elements that can be attracted by the magnet members 14 are provided at corresponding positions on the cover body 2.

It will be appreciated that the magnet component 14 may be a magnet or an electromagnetic component, while the component to be attracted may be an iron component or a magnet component arranged in a manner opposite to the magnetic poles of the magnet component 14. In an alternative embodiment, it is also possible to provide a magnet component on the cover 2 and to provide an element to be attracted at the energy filling port 1. In addition, according to the teachings of the present invention, those skilled in the art can set the shape and arrangement position of these components or elements according to specific needs, without being limited to the illustrated examples. The present embodiment effectively controls the single-point supported cover of the energy filling port by a low-cost and simple and reliable structure, so that when the cover is rotated to the position of the energy filling port, it can be accurately sucked into the card slot to avoid The left and right sway of the cover of the energy charging port ensures a good gap difference, improves the matching degree of the whole vehicle, and provides a larger space for the body design.

Based on the teachings of the present specification, those skilled in the art will appreciate that the various aspects of the foregoing embodiments may be combined with one another to form additional aspects, which are also within the scope of the present invention. In addition, in an alternative embodiment, in order to further improve the rebound and jitter problem of the cover body, it may be considered to provide a high viscosity liquid for generating damping between the mandrel and the sleeve; in specific use, as long as it is slippery The tank is filled with a high viscosity liquid to make it possible. It can be understood that the sealing problem of the liquid needs to be considered at this time, and the sealing design in the automobile shock absorber can be referred to. This solution can also be combined with the solution in any of the foregoing embodiments. Combine.

It can be understood that for a vehicle including the energy filling port assembly according to the present invention, at a lower cost, a simpler and more reliable structure, and an optimized design for key details, the cover is opened when the cover of the energy filling port is opened. There is no rebound and jitter at the end of the open stroke of the body, which advantageously improves the user experience during the opening process of the cover of the energy filling port assembly; at the same time, the gap surface difference when the cover is closed is improved, and the stability of the cover is maintained and Consistent with the body shape.

The technical scope of the present invention is not limited to the above description, and those skilled in the art can make various modifications, modifications and combinations to the above embodiments without departing from the technical idea of the present invention. Combinations are all within the scope of the invention.
